Answer: c
Step-by-step explanation:
Since each month profit is $1,900, it should be multiplied by 1900 as the time goes by. For example, one month profit is 1900, two month profits are 2*1900, three months profits are 3*1900, and so on...
So, it's Y (the amount of profits after X months) = 1900*X
The functions and their descriptions are:
- Polynomial:
and 
- Logarithm:

- Exponential

<h3>How to describe the functions?</h3>
The functions are given as:




The functions would be described based on the type of function they represent.
Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.
